Singing has been advocated as an efficient supplementary strategy in language teaching, but little is known about its effect on grammar learning. We conducted an intervention study (five lessons) with primary EFL learners (N = 57, mean age = 8.67, SD = 0.60) who were taught new vocabulary and grammar through either singing or speaking lyrics. The control group had new vocabulary introduced during regular lessons. Language gains were assessed through pre-, post-, and follow-up tests; affect was measured after each lesson. Students in the singing group showed similar vocabulary gains to students in the control group and larger gains than students in the speaking group. Importantly, singing students outperformed both groups on spelling and grammar learning. Positive affect was similar across intervention groups, but only the singing group showed significantly enhanced positive affect compared to the control group. Overall, results indicate a potential benefit of singing for grammar learning. 相似文献

本文提出了一种设计和实现英汉翻译系统的新方法。该方法以模板匹配替换通用算法 (UAMRT)为基础 ,通过结合句型分析算法和从句分析算法建立启发式搜索机制 ,实现从源语言句子到目标语言句子的自动翻译。它不仅能够合理地利用基于规则和基于例子的翻译系统的优点 ,而且能够在一定程度上克服它们的缺点。速度测试表明以该方法为基础实现的英汉翻译系统在P IV1 7G的计算机上的翻译速度每秒可以达到 130 0个单词左右 ;质量测试表明该系统具有较好的发展潜力 相似文献

邮政法修订之际,对邮政合同的定义的争论已达白热化。邮政合同的范围不应当等于邮政企业的业务范围。将邮政合同限定于普遍服务合同,不仅突出了邮政合同的社会服务的特殊性,而且也揭示了邮政的本源。 相似文献

This article offers an overview and analysis of recent early childhood education reforms in Great Britain. It examines the
national mandates to grant Universal Preschool Education to all three and four year olds as well as recent strides to provide
for infants and toddlers in model centers throughout the country. Attention is given to British practices and policies, research
findings and international implications. 相似文献

对句法的研究,传统的方法是作句子成分分析,分别找出句子的主谓结构。这种分析方法只是停留在单句结构平面上,无法解释它的结构形式和它所要表达的功能之间有什么样的联系,系统功能语法从语篇功能的角度将小句划分为主位和述位,弥补了传统语法中主语概念的局限性,本主要通过介绍主语和主位划分的异同,阐明主位概念对认识小句语篇功能的意义。章最后通过对具体语篇的主位研究,介绍了主位结构在篇章分析中的应用。 相似文献

动趋结构是否是“词”,这在语言学界仍有争议。本文试图以公众词感为事实基础,通过对动趋结构的语音形式和语义内涵的分析,认为动趋势结构自身稳定,凝固的语义内涵使得这一结构更接近于短语词。 相似文献

With the popularity of online educational platforms, English learners can learn and practice no matter where they are and what they do. English grammar is one of the important components in learning English. To learn English grammar effectively, it requires students to practice questions containing focused grammar knowledge. In this paper, we study a novel problem of retrieving English grammar questions with similar grammatical focus. Since the grammatical focus similarity is different from textual similarity or sentence syntactic similarity, existing approaches cannot be applied directly to our problem. To address this problem, we propose a syntactic based approach for English grammar question retrieval which can retrieve related grammar questions with similar grammatical focus effectively. In the proposed syntactic based approach, we first propose a new syntactic tree, namely parse-key tree, to capture English grammar questions’ grammatical focus. Next, we propose two kernel functions, namely relaxed tree kernel and part-of-speech order kernel, to compute the similarity between two parse-key trees of the query and grammar questions in the collection. Then, the retrieved grammar questions are ranked according to the similarity between the parse-key trees. In addition, if a query is submitted together with answer choices, conceptual similarity and textual similarity are also incorporated to further improve the retrieval accuracy. The performance results have shown that our proposed approach outperforms the state-of-the-art methods based on statistical analysis and syntactic analysis. 相似文献
